The method includes the actuator (1) dilating to a value Delta1, the pivoting feet (2) sliding on tracks (4), and the feet (3) supporting themselves on the tracks, and the feet sliding on the tracks, the elements (1,2,3) being displaced by a theoretical differential value and relatively equal to Delta1 with respect to the tracks and also, if this procedure is repeated f times per second, one obtains a displacement d = f x Delta1 per second. The motorized crawling method allowing the displacement and the very precise positioning of loads, using a device having a pulsing activator on which are fixed pivoting feet (2,3), pivoting on its ends (points A), inclined at an angle Theta, satisfying the condition tgTheta is less than TgPhi, (TgPhi = coefficient of friction between the feet with respect to the tracks (4)), these feet supporting themselves alternatively on the tracks, when the actuator dilates itself in order to contract. |
